Abstract (en)

A system for controlling a power distribution network providing power using a plurality of phases comprises an electronic processor and memory storing instructions that, when executed by the electronic processor, cause the system to receive a loss of voltage fault indication associated with a fault in the power distribution network. The electronic processor identifies a first subset of the plurality of phases associated with the loss of voltage fault indication and a second subset of the plurality of phases not associated with the loss of voltage fault indication. The first and second subsets each include at least one member. The electronic processor identifies a downstream isolation device downstream of the fault. The electronic processor sends an open command to the downstream isolation device for each phase in the first subset. The electronic processor sends a close command to a tie-in isolation device downstream of the downstream isolation device.
